Description

Ceramic silicon coating fabric and manufacturing method thereof {Ceramic silicon coating and fabric manufacturing method using the same}

The present invention relates to a method for manufacturing a ceramic silicon-coated fabric and a manufacturing method thereof.

Silicon is extracted from quartz sand, a natural material. Silicon is obtained by heating quartz sand at a high temperature of about 4000℃ to extract metal silicon and then combining it with oxygen. Silicone is a necessary and most widely used material in modern industry due to its various characteristics such as flame retardancy, excellent electrical insulation, chemical resistance, heat resistance, cold resistance, non-toxicity, and eco-friendliness. For example, it is widely used for products that require a high degree of non-toxicity, such as implants or moldings inserted into the human body and baby nipples. In addition, it is widely used in high-tech industries such as semiconductors, automobiles, and spacecraft due to its excellent electrical insulation, heat resistance (320℃), and cold resistance (-52℃).

Silicone coated fabric is a functional fabric manufactured by coating fabric with high-purity liquid-type silicone among silicones, which are non-toxic and eco-friendly materials. Silicone coated fabric is in the limelight as an eco-friendly natural material fabric that reduces environmental pollution by replacing natural leather that emits pollutants and harmful substances and synthetic leather manufactured by laminating PVC or PU. In addition, it has flame retardant and flame retardant properties that do not generate flame or toxic gas even in the event of a fire, so it has an advantage in terms of safety of furniture materials, interior materials, and finishing materials.
